Wow, this brings back some memories. I got hired as a SysProg at a company migrating from a System/3 to a 4331. I also had heavy knowledge in RPG programming. About 3 years later we upgraded to a used 4361, I don’t remember the model number. It was maxed out on memory, well as much as the 4361 could support. It also had a Token Ring card in it, of all things. The IBM CE said it was the first T/R card he’d ever seen in a 4361. We never got to use it as the building wasn’t wired for that type of network or any network for that matter. We were still using coax cable. Oh, and we only ran VSE on it. It was a great little system.
I was a sophomore in High School that year. The university in the next town over ran all HP system in the computer room in the basement with terminals all over campus. Wow I had to edit this. I put two things together. The high school I went to used DEC and no they don't.
We had a 4381. for end user computing running VM/CMS.. If I remember correctly, one of its big advantages over our production 3090s was it didn't need water cooling. It also ran PROFS IBMs version of an office productivity suite. EMAIL, Messaging.
Fun fact: the 4300 series was meant to run VSE not VM or MVS. This was due tonthe fact that is had imomented the DAT in hardware not software amd VSE utilised this capability very well so jobs ran much faster using VSE
IBM 4300 DISASTER: I worked at PACE university(1980) in nyc, we had a IBM 360/50 running MUSIC(mc gill university time sharing system), The music system ran great. Students from 2 campuses used the terminals. Students quickly learned the music system, I found it very easy to teach COBOL on the system. THEN THE 4300 DISASTER: The morons running the college switched to a IBM 4341 running ibm VM. Mary Beth the new IT director, never bothered to tell the faculty that EVERYTHING will be new WHEN EVERYONE RETURNS IN THE FALL!!(FROM SUMMER VACATION) AND DIFFERENT. she offered no manual for mvs or vm OR TSO, and no training for the faculty on the new system!!! THE MANAGEMENT OF PACE UNIVERSITY DID NOT CARE THAT NOTHING WORKED, THE NEW 4300 RAN SO SLOW IT COULD NOT HANDLE THE 2 CAMPUSES. IT BECAME A JOKE SYSTEM. NYC CAMPUS GOT ONE HOUR ON THEN OFF FOR AN HOUR! WESTCHESTER GOT ONE HOUR ON THEN ONE HOUR OFF!!!. MORAL OF THE STORY: THE 4300 WAS A DOG,, THE MANAGEMENT OF PACE UNIVERSITY NAIVE AND INCOMPETENT(LIKE MOST UNIVERSITY MANAGEMENT). AFTER THAT EXPERIENCE, I ALWAYS HATED THE 4300 MACHINE AND WOULD ALWAYS RECOMMEND ANY OTHER MACHINE TO MY CLIENTS. I was quite happy to see Microsoft server and linux take over the computer market and IBM become a jokei
Go ahead. Blame the machine. We replaced a System 370/155 at GTE/Sylvania with a 4341 in 1980 running DOS/VS under VM, and it ran like a screaming bat out of Hell.
Well, I'll take a moment to disagree. I ran an entire life insurance company on a pair of 4341s. VM/SP, DOS/VSE, and CICS. A mix of shared 3350 and FBA DASD. The trick was configuring and tuning it properly. Stability was fairly good, maybe a crash every week or two and then confined to one of the VSE virtual machines. I loved that setup.
@comp: I can see that happening if the machine wasn’t sized correctly. I ran VM and VSE under VM most of my career and they played well together. The thing is you gotta know how to tune the hardware and operating systems.

I used this series as an operator. Including vm, test and production vms running vse

A punched card reader? On an IBM mainframe in 1992? What in the name of hell was it used for? Who used those antiques then?
We did. The card reader was rarely used but was used on occasion for 1 or 2 legacy prosesses.
@@DELLTelevision : same here. We had some legacy systems and were gradually migrating off cards and putting the JCL online.
Do you still run VSE?
No we do not run VSE any longer in fact it's been may years since. Today we are running Z/OS
@@DELLTelevision What was the reason for choosing VSE over MVS back in those days?
@@macieksoft Truthfully it was about cost. We eventually converted to MVS a short time later.
no, ZOS
@@macieksoftfact: the 4300 series was meant to run VSE. It runs faster than VM or MVS on the 4300 series

@@pking147king6 Nice. You can run DOS/VS under VM/370 today using Hercules to emulate IBM hardware on your desktop computer.

Correct running VM or MVS on a 4300 series machine will be drastically slower as this was mean to run VSE
An interesting look at antediluvian computer technology. 💾
